Achievements? What do they unlock?
 

Is this just for Xbox? Unlocking achievements grants what bonus? My character was killed off by a Slaughter Fish and I received an achievement for this. WTF Zenos lol

I asked the same question on ESO forum during the last beta. They told me that Archievements not give bonus.

Generally, Achievements are something to brag about or have as trophy of something you've achieved. People who are more interested in lore and exploration might find it of more interest.

They are just bragging rights, and some achievements have rewards, such as titles.

Oh ok thanks for the information

They will probably give rewards down the road. Titles, and rewards.
